I am a board-certified otolaryngologist - which is a head and neck surgeon. A Phi Beta Kappa graduate from UCLA with highest honors, I graduated with distinction from the UCSD School of Medicine in 1996. I had my "calling" at age five when my newborn sister was born with a congenital condition. I was so impressed with the care she received from her physicians, that I made a vow to become a doctor so I could help other people in the way the doctors helped my sister. I have authored several publications and have given many presentations in the field of otolaryngology. I have a special interest and expertise in thyroid and parathyroid surgery, endoscopic sinus surgery and nasal surgery, otologic microsurgery and facial plastic and reconstructive surgery. In my spare time, I race cars, travel extensively, attend musicals, concerts and cultural events and try to enjoy San Diego for all it has to offer.

He didn't spend any time with me. I did not feel heard, so I stopped talking. I know he didn't believe me when I described my symptoms, because there was nothing on the scan, I knew he wouldn't. If a symptom is not screaming at them in the face you're a liar or at least that is the way it feels. No one is interested in helping me with this sinus issue. That is painfully clear. There was nothing for the Dr. Mathisen to operate on he had no interest in me. Plus his son was visiting so his focus certainly wasnt on me.
